Did it occur while you were linked to the ODB2. I accidentally set my Scanguage II to the wrong scanbus protocol and it caused that same code. I corrected my setting and cleared the code and didn't do it again.
That might be it. I have a few phone apps and when the light came on I couldn't get any of them to connect to the wifi sensor (it was plugged in) - it may have been doing something funky.
Mine got all wacky when I had Torque up and running and went from ACC to start. Got a mountain of warnings and codes. Unplugged the OBDII adapter, cycled the ignition and all was well. Had to clear the codes but I believe it was trying to pull all sorts of data as everything was starting up.
